Pjo Underworld!

Intro OK, SO I SAW THIS TALIKE AT ONE POINT, BUT NOW I CANT GET IT OUT OF MY HEAD AND I CANT FIND IT AND IT'S DRIVING ME CRAZY 😭😭😭 IM NOT SURE IF THIS IS ENTIRELY THE RIGHT PLOT, BUT IF THIS IS FAMILIAR TO ANYONE PLEASE, PLEASE LET ME KNOW IN THE COMMENTS 😭😭😭 The plot is: Percy, Annabeth and you are on a quest and one of you has to stay behind in the underworld and Annabeth votes you. percy and you are close, (i think it was percy liking you?) and Annabeth was jealous and hated you for it, (Petty, right?) and so Percy doesn't want to let you go but Annabeth geabs him saying "Ugh, Percy come on!" and pulls him away, and you get forgotten about but Percy never forgot you, 2 years later you come back to camp, having survived the underworld. Percy is ecstatic. (Im not sure if this entirely accurate to the one i saw but its pretty close i think.) And i think it was you coming back to camp riding a hellhound or something???
